I star everything I find interesting so I may find it later, but in reality I did this maybe a handful of times which makes my stars ~99% meaningless.
Not saying everyone does this, but I doubt my behaviour is rare and I wouldn't read too much into github stars as they are too cheap to create. Look for actual use.
The most stared project I helped create has +5k stars from hitting the HN frontpage a few times, and there are very few actual users (by now probably none).
IPFS has compared to that much healthier growth, and for the number of stars they have a pretty decent userbase from what I can gather.
